Screenshot with difference between Windows and WINE

An image static control does not seem painting the background around the image
with the right color.
The default color used for filling the area around the image is not
COLOR_BTNFACE (I guess you selected that one) but instead it seems to be filled
with a solid brush created with the color in the origin of the image, at
coordinates (0,0).
I attached a screenshot that it shows the difference between the expected
result and the current result obtained in WINE.
This is a trick tipically used to reduce the size of the bitmap since the image
control "expands" the color we want without any additional work.
Sometimes you can see this artifact in some "about box" of some software,
however I also attached a demo programme that you can use to reproduce the
defect.

Sincerely,

Carlo Bramini
